Although this form of oocyte degeneration has been mentioned and/or described in mature and residual oocytes in Pectinidae
(Tang 1941, Christiansen & Oliver 1971, Dorange & Le Pennec 1989, Motavkine & Varaksine 1989, Le Pennec et al.
Number of species of bivalves distributed in each family reveals that 12 species belongs to family Veneridae, 5 species to Arcidae, 3 species to Ostreidae and 2 species to Pectinidae
Thin-shelled bivalves such as Pectinidae
from fine quartz sands are generally represented by small fragments, this means resedimentation process in situ or an incipient reworking.
Family Veneridae recorded the most abundant (1917 bivalves, 85% of the recorded bivalves) while families Mytiloidea, Ostreidae, Plicatuloidea, Pectinidae
, Spondylidae, Carditoidea and Arcticoidea were represented by less than ten valves for each (Table II, Fig.

Los pectinidos se encuadran sistematicamente dentro de la familia Pectinidae

In present study, bivalves belonging to families Arcidae, Ostreidae, Pectinidae
, Placunidae, Corbiculidae, Psammobiidae, Trapezidae and Veneridae were recorded.
